The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar
1 Pa = 10-5 bar
1 in = 2.54 cm
1 cm = 10...
Air pressure is measured by a barometer. One type of barometer utilizes an evacuated, calibrated tube inverted in a pool of mercury that is open to the atmosphere. As air pressure increases, the mercury will rise in the column until the weight of the mercury in the column equals the force exerted by the air on the surface of the pool. The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg ). According to this barometer,...
atmospheric pressure is 25.65 inches of mercury. Convert inches of mercury to Torr. ( there are 2.54cm to the inch )

A barometer is an instrument used to measure atmospheric pressure. In a unit conversion, equivalent to 29.92 inches of mercury (usually written as just 29.92). ay A muid pressure that many people are aware of is their own blood pressure. A doctor typically w something like, "your blood pressure is 120 over 80". Questions: 1) What are the units for blood pressure? (hint, it is not psi) 2) What is the meaning of the two numbers - the 120 ?...
1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...
